Inertia Matrix

Some articles on inertia matrix, inertia:

Inertia Tensor - Moment of Inertia Reference Frames
... The use of the inertia matrix in Newton's second law assumes its components are computed relative to axes parallel to the inertial frame and not relative ... that as the body moves the components of the inertia matrix change with time ... In contrast, the components of the inertia matrix measured in a body-fixed frame are constant ...
Inertia Tensor - Moment of Inertia Reference Frames - Inertia Ellipsoid
... The moment of inertia matrix in body-frame coordinates is a quadratic form that defines a surface in the body called the inertia ellipsoid ... Let be the inertia matrix relative to the center of mass aligned with the principal axes, then the surface or defines an ellipsoid in the body frame ... unit vector, then from the definition of the inertia matrix, where In is the moment of inertia of the body around the axis in the direction n ...

Famous quotes containing the words matrix and/or inertia:

    In all cultures, the family imprints its members with selfhood. Human experience of identity has two elements; a sense of belonging and a sense of being separate. The laboratory in which these ingredients are mixed and dispensed is the family, the matrix of identity.
    Salvador Minuchin (20th century)

    What is wrong with priests and popes is that instead of being apostles and saints, they are nothing but empirics who say “I know” instead of “I am learning,” and pray for credulity and inertia as wise men pray for scepticism and activity.
    George Bernard Shaw (1856–1950)
